Each packet contains 50 perfect shells ready for your artwork. I always add a couple of extra ones in case you find a flaw that I missed.
Colors from left to right, top to bottom are-
Dark pink (out) -- Red
Peach (out) -- Red/orange (out) -- Orange
Blue -- Yellow -- Natural white
These are only available in red, orange, blue and yellow.
The shells average only 1/8" across.
